The ESP Timeline (one of the site's most popular features) has been
completely updated to allow the user to select (using the timeline controls
above each column) different topics for
the left and right sides of the display.

Miners at Broken Hill in the British colony of Northern Rhodesia, Africa, find leg bones and a skull that will later be classified as Homo heidelbergensis.

Kodak makes 35 mm panchromatic motion picture film available as a regular stock.

1922

Lillian V. Morgan discovers attached-X chromosomes in Drosophila.

The American Museum of Natural History begins a series of excavations in central Mongolia, led by Roy Chapman Andrews. Hoping to find fossil human remains, Chapman's team instead finds dinosaurs.

Integrated Circuit Co-Inventor Jack Kilby is Born

Harold Edgerton invents the xenon flash lamp for strobe photography.

The 16 mm amateur motion picture format is introduced by Kodak. Their Cine-Kodak camera uses reversal film and all 16 mm is on an acetate (safety) base.

1923

A. E. Boycott and C. Diver describe "delayed" Mendelian inheritance controlling the direction of the coiling of the shell in the snail Limnea peregra. A. H. Sturtevant suggests that the direction of coiling of the Limnea shell is determined by the character of the ooplasm, which is in turn controlled by the mother's genotype.

Winifred Goldring publishes a description of a fossil forest discovered during excavations for the Gilboa Dam. Dating from the Devonian Period, the site will become known as the world's oldest fossil forest.

Tennessee schoolteacher John Thomas Scopes is tried for teaching evolution in the famous "Scopes Monkey Trial." Two-time presidential candidate William Jennings Bryan leads the prosecution. Labor lawyer Clarence Darrow leads the defense and goads Bryan into declaring that humans are not mammals. The conviction will be overturned on a technicality, and the anti- evolution law will remain on the books for decades.

A. H. Sturtevant analyzes the Bar-eye phenomenon in Drosophila and discovers position effect.

Francis Turville-Petre finds Galilee Man, the first fossil hominid discovered in Western Asia. The fossil will later be dated to more than 250,000 years old, and classified as neither modern Homo sapiens nor Neanderthal.

Raymond Dart publishes a description of the "Taung Child," a hominid child's skull from Africa. He classifies it as Australopithecus africanus and concludes that it's the missing link between humans and apes.

Kodak introduces its 35 mm Motion Picture Duplicating Film for duplicate negatives. Previously, motion picture studios used a second camera alongside the primary camera to create a duplicate negative.

H. J. Muller reports the artificial induction of mutations in Drosophila by x-rays.

J. B. S. Haldane suggests that the genes known to control certain coat colors in various rodents and carnivores may be evolutionarily homologous.

Excavations in Kent's Cavern in southern England turn up a fragment of a human upper jaw, roughly 43,000 years old. Arthur Keith will provisionally identify it as anatomically modern human, and this finding will be confirmed in a 2011 study.

Frederick Griffith discovers type-transformation of pneumococci. This lays the foundation for the work of Avery, MacLeod, and McCarthy (1944).

L. J. Stadler reports the artificial induction of mutations in maize, and demonstrates that the dose-frequency curve is linear.

In a letter to Science, Louise Sudbury states that fossil plants, Cycadeoidea Etrusca, were collected by Etruscans over 4,000 years ago.

In trying to piece together a Burgess Shale organism over 500 million years old, Danish zoologist K. L. Henriksen glues an Anomalocaris appendage to a Tuzoia carapace to make what he thinks is a reasonable looking shrimp-like animal. This mistaken interpretation will persist for years.

John Henry Pull, a postman and amateur archaeologist, finds fossil urchins in two separate Neolithic burial sites. His efforts to publish on his findings, however, will be thwarted due to his pedestrian background.

1929

Davidson Black announces the find of Sinanthropus pekinensis, or Peking Man, discovered at Zhoukoudian, China. Over the next several years, five nearly-complete skulls will be recovered from the same site. Peking Man will be lost, however, during World War II.

In the early 1990's,
Robert Robbins
was a faculty member at Johns
Hopkins, where he directed the informatics core of GDB
— the human gene-mapping database of the international human
genome project. To share papers with colleagues around the world, he
set up a small paper-sharing section on his personal web page. This
small project evolved into The Electronic Scholarly
Publishing Project.

ESP Support

In 1995, Robbins became the VP/IT of the Fred Hutchinson Cancer Research
Center in Seattle, WA. Soon after arriving in Seattle, Robbins secured
funding, through the ELSI component of the US Human Genome Project, to
create the original ESP.ORG web site, with the formal goal of
providing free, world-wide access to the literature of classical genetics.

ESP Rationale

Although the methods of molecular biology can seem almost
magical to the uninitiated, the original
techniques of classical genetics are readily appreciated by one and
all: cross individuals that differ in some inherited trait, collect
all of the progeny, score their attributes, and propose mechanisms
to explain the patterns of inheritance observed.

ESP Goal

In reading the early works of classical genetics, one is drawn, almost
inexorably, into ever more complex models, until molecular explanations
begin to seem both necessary and natural. At that point, the tools
for understanding genome research are at hand. Assisting readers reach
this point was the original goal of The Electronic Scholarly Publishing
Project.

ESP Usage

Usage of the site grew rapidly and has remained high. Faculty began
to use the site for their assigned readings. Other on-line
publishers, ranging from The New York Times to Nature
referenced ESP materials in their own publications. Nobel laureates
(e.g., Joshua Lederberg) regularly used the
site and even wrote to suggest changes and improvements.

ESP Content

When the site began, no journals
were making their early content available in
digital format. As a result, ESP was obliged to digitize classic
literature before it could be made available. For many important
papers — such as
Mendel's original paper
or the
first genetic map
— ESP had to produce entirely new typeset versions of the works,
if they were to be available in a high-quality format.

ESP Help

Early support from the DOE component of the Human Genome Project was
critically important for getting the ESP project on a firm foundation.
Since that funding ended (nearly 20 years ago), the project has been
operated as a purely volunteer effort.
Anyone wishing to assist in these efforts should send an
email to Robbins.
